Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sound barriers, specifically a sound barrier with drainage function. Background Technology
[0002] With the increasing prevalence of highways and urban roads, sound barriers have become a widely used core facility for reducing traffic noise. Traditional sound barriers primarily focus on optimizing acoustic structures, such as using porous sound-absorbing materials and micro-perforated panels to improve noise reduction, but generally neglect drainage design, revealing the following shortcomings in practical use:
[0003] During rainy weather, rainwater flows vertically down the surface of the barrier and accumulates at the base. Most existing bases are closed structures, and long-term water accumulation causes the barrier to rust. In addition, the sound barrier blocks the roadside, forming local depressions where water cannot drain quickly, increasing the risk of vehicles skidding. Therefore, it is necessary to design a sound barrier with drainage function. Utility Model Content
[0004] The purpose of this invention is to provide a sound barrier with drainage function, thereby achieving both drainage and noise reduction.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a sound barrier with drainage function, characterized in that it includes a base part, a barrier part installed on the base part, and a support part disposed on both sides of the barrier part;
[0006] The base portion has a drainage cavity inside, and a drainage groove communicating with the drainage cavity is opened on its top surface. A water leakage hole is provided in the middle of the bottom wall of the drainage groove.
[0007] The bottom wall of the drainage trough is inclined with a lower middle and higher ends, and the slope is directed towards the drain hole;
[0008] The barrier section has several guide strips on the side facing the highway.
[0009] In a further technical solution, the support portion includes a support frame, with first splicing grooves symmetrically opened on both sides of the support frame, and a second splicing groove connected to the bottom of the first splicing groove;
[0010] The barrier section includes a barrier plate, the bottom of which is provided with a splicing part that slides with the second splicing groove, and both sides of the barrier plate can slide into the first splicing groove.
[0011] In a further technical solution, the guide strip is vertically arranged;
[0012] The guide strip is composed of an arc-shaped noise reduction plate and a guide plate, and the guide strip and the interior of the barrier plate are filled with sound-absorbing material.
[0013] In a further technical solution, a rain shield is provided on the top of the barrier plate, and the two ends of the rain shield are fixed to the top of the support frame by a detachable connection.
[0014] In a further technical solution, a permeable plate is installed on the side of the drainage cavity facing the highway, and the outer surface of the permeable plate is flush with the side of the base plate.
[0015] A further technical solution is that a recessed platform is provided at the top opening of the drainage trough, and a filter plate can be detachably installed on the recessed platform. The surface of the filter plate is provided with uniformly distributed filter holes.
[0016] In a further technical solution, the drainage chamber is connected to a drainage pipe on the side facing away from the road, and a water outlet chamber is opened inside the drainage pipe.
[0017] A further technical solution is provided in the water outlet cavity, wherein the top of the swing baffle is hinged to the top wall of the water outlet cavity, and the bottom wall of the water outlet cavity is provided with an inclined surface that restricts the swing baffle to open only to the side away from the road.
[0018] In a further technical solution, the bottom wall of the drainage cavity is set to gradually decrease from the road side to the side away from the road.
[0019] In a further technical solution, the support frame is fixed to the base portion via a detachable connection structure;
[0020] The base portion includes a base plate, and the top surface of the base plate is provided with splicing threaded holes for mounting the bracket frame.
[0021] In summary, this utility model has the following beneficial effects:
[0022] The rainwater sprayed on the barrier panel is guided by the guide strips to flow in a direction to the drainage channel. The inclined bottom wall of the drainage channel causes the rainwater to converge towards the drain hole. Combined with the filter plate to block large particles of impurities and avoid blockage, the permeable plate directly drains the water on the road surface, preventing the road from being difficult to drain due to the installation of the sound barrier and reducing the risk of road water accumulation.
[0023] The one-way swing baffle inside the drain pipe only allows rainwater to drain outwards, preventing animals from entering the drain cavity in the opposite direction.
[0024] The curved noise reduction plate and the deflector plate can not only guide rainwater, but also improve noise absorption efficiency;
[0025] The rain shield prevents rainwater from seeping into the barrier and keeps the sound-absorbing material dry.
[0026] The support and barrier sections are slidably assembled via splicing grooves, and the base section offers options for buried or ground anchoring, adapting to different construction scenarios and improving the convenience of installation and maintenance. Attached Figure Description

[0045] like Figures 1-11 As shown, a sound barrier with drainage function includes a base portion 100, a barrier portion 300 is installed on the base portion 100, and support portions 200 are installed on both sides of the barrier portion 300.
[0046] Specifically, a base portion 100 is equipped with three barrier portions 300 and four support portions 200, with the support portions 200 and the barrier portions 300 spaced apart.
[0047] In one embodiment, the support portion 200 includes a support frame 201, with a first splicing groove 202 on both sides of the support frame 201, and a second splicing groove 203 connected to the bottom of the first splicing groove 202. The first splicing groove 202 and the second splicing groove 203 are used to splice and assemble with the barrier portion 300.
[0048] In one embodiment, the barrier portion 300 includes a barrier plate 301. A splicing portion 304 is provided at the bottom of the barrier plate 301, which is slidably inserted into the second splicing groove 203. Uniformly distributed guide strips 302 are provided on the side of the barrier plate 301 facing the road. The guide strips 302 are vertically arranged and can guide rainwater. Each guide strip 302 comprises a noise-reducing plate 302A and a guide plate 302B. The noise-reducing plate 302A and the guide plate 302B are filled with sound-absorbing material, such as sound-absorbing cotton. The barrier plate 301 is also filled with sound-absorbing material. The noise-reducing plate 302A is arc-shaped, which can scatter sound and improve the noise reduction effect. The arrangement of the noise-reducing plate 302A and the guide plate 302B can guide the flow of rainwater and absorb some noise, enhancing the noise reduction effect.
[0049] Specifically, the guide strips 302 ensure that rainwater falling on the barrier plate 301 is evenly separated by several guide strips 302, and then the rainwater is evenly guided into the drainage ditch 104 in several parts. This prevents the rainwater falling on the barrier plate 301 from being concentrated into one or only a few flow paths due to dust or other reasons that may adhere to the barrier plate 301, which would prevent the drainage ditch 104 from collecting the rainwater flowing down the barrier plate 301 evenly, and thus prevent it from flowing directly onto the road.
[0050] In one embodiment, a rain shield 303 is installed on the top of the barrier panel 301 to cover the top of the barrier panel 301 and prevent rainwater from entering the barrier panel 301 through the opening filled with absorbent material on the top of the barrier panel 301.
[0051] In one embodiment, the base portion 100 includes a base plate 101, in which a drainage cavity 106 is formed that runs through the front and back. A drainage groove 104 is formed on the top surface of the base plate 101. A drain hole 105 communicating with the drainage cavity 106 is formed in the middle of the bottom wall of the drainage groove 104. The bottom wall of the drainage groove 104 is designed to be inclined, and the height gradually decreases from both ends to the drain hole 105 in the middle. This design allows rainwater to gather at the drain hole 105 and flow into the drainage cavity 106. In addition, the bottom wall of the drainage groove 104 is arc-shaped, which facilitates rainwater to wash some dust into the drainage cavity 106 and prevents dust from accumulating in the drainage groove 104.
[0052] A permeable plate 102 is installed on the side of the drainage chamber 106 facing the road. The permeable plate 102 can allow rainwater to pass through, so that rainwater from the road can flow into the drainage chamber 106 through the permeable plate 102 and be discharged to the side of the sound barrier away from the road, thus preventing water accumulation on the road between the sound barriers.
[0053] The permeable board 102 can be a perforated brick or a permeable brick.
[0054] In one embodiment, a recessed platform 103 is provided at the top opening of the drainage trough 104. The recessed platform 103 is used to install a filter plate 400. The filter plate 400 is provided with evenly distributed filter holes 401 to filter larger impurities and prevent larger impurities, such as leaves, weeds, plastic bags, etc., from entering the drainage trough 104 and blocking the drain hole 105, thus preventing drainage.
[0055] In one embodiment, a drain pipe 107 is fixed to the opening of the drainage chamber 106 on the side away from the road. A water outlet chamber 109 is provided inside the drain pipe 107. The water outlet chamber 109 is connected to the drainage chamber 106 and is used to drain the rainwater in the drainage chamber 106. A swing baffle 108 is provided in the water outlet chamber 109. The top of the swing baffle 108 is hinged to the top wall of the water outlet chamber 109. The bottom wall of the water outlet chamber 109 is inclined so that the swing baffle 108 can only open towards the side away from the road, which is used to prevent small animals, such as mice and rabbits, from entering the drainage chamber 106 through the water outlet chamber 109.
[0056] In one embodiment, the bottom wall of the drainage cavity 106 is inclined, and the inclination direction gradually decreases from the side closer to the road to the side away from the road.
[0057] In one embodiment, the base plate 101 is provided with a plurality of splicing threaded holes 110, and the bracket frame 201 is provided with holes. Bolts are inserted into the holes by means of screw fastening and then tightened into the splicing threaded holes 110, so that the bracket frame 201 and the base plate 101 are spliced and assembled.
[0058] In one embodiment, the rain shield 303 is fastened to the support frame 201 by bolts. For example, round holes are provided at both ends of the rain shield 303, and threaded holes are provided at the top of the support frame 201. The rain shield 303 is fixed to the support frame 201 by inserting screws and tightening them.
[0059] In one embodiment, the bottom of the base plate 101 can be extended to bury the sides of the road in the soil; or the soil on both sides of the road can be hardened, for example, by laying cement, and then the base portion 100 can be placed on the cement, and fixed to the cement surface by drilling holes in the base plate 101 and inserting connecting rods.
[0060] The installation of a sound barrier with drainage function according to this application is as follows:
[0061] The sound barriers of this application are installed on both sides of the highway, wherein the side with the guide strip 302 structure faces the highway;
[0062] During installation, the base plate 101 is first installed on both sides of the highway. Then, one of the bracket frames 201 is fixed to the base plate 101 with bolts. Next, the barrier part 300 is installed. One side of the barrier plate 301 is inserted into the guide strip 302, and the splicing part 304 is inserted into the second splicing groove 203. Then, the other bracket part 200 is spliced and assembled with the barrier part 300 and fixed to the base part 100 with bolts. This process is repeated to complete the assembly of the sound barrier of this application.
[0063] The working principle of a sound barrier with drainage function proposed in this application is as follows:
[0064] When it rains, the rainwater that falls on the barrier section 300 is guided by the guide strip 302, filtered by the filter plate 400, and flows into the drainage trough 104. Then, because the bottom wall of the drainage trough 104 is inclined and has an arc-shaped surface, the rainwater gathers in the middle of the drainage trough 104 and flows into the drainage chamber 106 through the water leakage hole 105. Then, the water on the road can seep into the drainage chamber 106 through the permeable plate 102, and then enter the water outlet chamber 109, impacting the swing baffle 108, causing the swing baffle 108 to open, and then discharge, completing the process of rainwater being discharged from the side of the sound barrier close to the road to the side away from the road.

[0066] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
